Best ResponseYou've already chosen the best response.0\[\int\limits_{}^{}\ln (\sqrt[3]{x})\] That is x to the 3 root

Best ResponseYou've already chosen the best response.0it might help to think of the cube root of x as x^(1/3)

Best ResponseYou've already chosen the best response.0then use the power rule

Best ResponseYou've already chosen the best response.0ok I got as far to as thinking of x^(1/3) lol

Best ResponseYou've already chosen the best response.0now use the rule that integral of x^n = (1/(n+1))*x^(n+1)

Best ResponseYou've already chosen the best response.0so do u mean put 1/3 in front of the ln of stuff and then put it in front of the entire integral? bc that's what I did and it said it was wrong = (

Best ResponseYou've already chosen the best response.0there's no ln involved here

Best ResponseYou've already chosen the best response.0ok maybe you should write the whole thing out cuz now you're just confusing me, please, thank you

Best ResponseYou've already chosen the best response.0no yeah i already know that lol we're in the chapter of integration by parts and there is a ln involved it's in the front of the x^(1/3)

Best ResponseYou've already chosen the best response.0not to interrupt, but i think the starting point here is \[\frac{1}{3}\int \ln(x)dx\] which you do either by parts or by memory

Best ResponseYou've already chosen the best response.0oh my bad, i didn't see the ln at the very beginning just thought it was cube root of x

Best ResponseYou've already chosen the best response.0since \(\ln(x)\) is a very common function, it might be benificial just to memorize \[\int \ln(x)dx=x\ln(x)x\] you can check by differentiation

Best ResponseYou've already chosen the best response.0yes that's what i did. oh damn nvm hahaha i think i get it I keep getting it confused that the derivative of ln is 1/x and we don't know the integral of ln yet so we have to do integration by parts lol

Best ResponseYou've already chosen the best response.0your answer is therefore \[\frac{1}{3}\left(x\ln(x)x \right)\]

Best ResponseYou've already chosen the best response.0i would memorize it just like remembering that \[\frac{d}{dx}\sqrt{x}=\frac{1}{2\sqrt{x}}\]so while your fellow classmates are integrating by parts, you just write down the answer

Best ResponseYou've already chosen the best response.0i won't recommend that method

Best ResponseYou've already chosen the best response.0what about\[\int\limits \ln e^{^{x ^{2}}}dx\]

anonymous

Best ResponseYou've already chosen the best response.0\[\int\limits \ln(x^2+2x+1)dx\]

Best ResponseYou've already chosen the best response.0so these are 3 examples that can't be used by just memorizing the specific case

anonymous

Best ResponseYou've already chosen the best response.0so basically use integration by parts like ur class mates
